Solve 25d^2 45d - 81 = 0

Evaluate

25 d^{2} \times 45 d - 81 = 0

Multiply

More Steps

1125 d^{3} - 81 = 0

Move the constant to the right-hand side and change its sign

1125 d^{3} = 0 + 81

Removing 0 doesn't change the value,so remove it from the expression

1125 d^{3} = 81

Divide both sides

\frac{1125 d ^{3}}{1125} = \frac{81}{1125}

Divide the numbers

d^{3} = \frac{81}{1125}

Cancel out the common factor 9

d^{3} = \frac{9}{125}

Take the 3 -th root on both sides of the equation

3 d^{3} = 3 \frac{9}{125}

Calculate

d = 3 \frac{9}{125}
